Resumo: | In view of the increasing search for natural products with biological activities, such as essential oils are of high quality because of their therapeutic and economic importance and represent the second class of natural compounds with the largest number of active constituents and production through Plants minimizes the environment and sanitary impacts . The objective of the present work is to assess the seasonal effect on the composition and antioxidant activity of essential oil in leaves of Plectranthus amboinicus (Lour.) Spreng using hydro and steam distillation techniques. With regarding to the extraction methodology of essential oils from the P. amboinicus, the hydrodistillation technique is the most efficient in obtaining the volatile product with the best features for the determination of antioxidant activity. The analyses of the essential oil indicated a similarity in their composition, being observed the Carvacrol as major compound in almost all analysis, except in January 2015 using steam distillation extraction. Regarding antioxidant activity and seasonality, it was verified that in October 2014 obtained the best value of inhibitory concentration, with IC50 = 124.97 ppm. However, it was possible to obtain the essential oil from the P. amboinicus leaves through hydro and steam distillation methodologies, but also noted the seasonality influence on it's the context of antioxidant capacity. |

Tendo em vista a crescente busca de produtos naturais com atividades biológicas, os óleos essenciais apresentam alta qualidade devido à sua importância terapêutica e econômica e representam a segunda classe de compostos naturais com o maior número de constituintes ativos com produção através das plantas, o que minimiza os impactos ao meio ambiente. O objetivo do presente trabalho foi avaliar o efeito sazonal na composição e na atividade antioxidante do óleo essencial presente nas folhas da Plectranthus amboinicus (Lour.) Spreng utilizando as técnicas de hidrodestilação e arraste a vapor d’água. No que se refere à metodologia de extração dos óleos essenciais do malvarisco, constatou-se que a técnica de hidrodestilação é a mais eficiente na obtenção do produto volátil com as melhores características para a determinação da atividade antioxidante. Quanto à sazonalidade, verificou-se que no mês de Outubro/2014 obteve-se o melhor valor da concentração inibitória com CI50=124,97 ppm. Este trabalho mostra que é aobtenção do óleo essencial das folhas do malvarisco, utilizando as metodologias de hidrodestilação e arraste a vapor de água, como também, constatar a influência da sazonalidade na determinação da capacidade antioxidante do mesmo.EDUFU2017-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3715410.14393/BJ-v33n6a2017-37154Bioscience Journal ; Vol. 33 No. 6 (2017): Nov./Dec.; 1608-1616Bioscience Journal ; v. 33 n. 6 (2017): Nov./Dec.; 1608-16161981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/37154/21206Brazil; ContemporaryCopyright (c) 2017 Rita de Cássia de Freitas Bezerra, Francisco Barros de Oliveira Neto, Francisco Felipe Maia da Silva, Luciana Medeiros Bertini, Leonardo Alcântara Alveshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBezerra, Rita de Cássia de FreitasOliveira Neto, Francisco Barros deSilva, Francisco Felipe Maia daBertini, Luciana MedeirosAlves, Leonardo Alcântara2022-02-12T01:35:43Zoai:ojs.www.seer.ufu.br:article/37154Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-12T01:35:43Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
